4 Claims. (Cl. 4-144) The present invention relates to an improvement of the known dry toilets sealing the collecting receptacle for waste matter in the sealing section by means of a water proof disc, that will be renewed after each usage, i. e. by actuating a plunger disc which presses the cardboard disc being dropped before closing the cover into the annular groove of the sealing section whereby at the same time the cardboard sealing already odorless will be discharged. The feeding of the fresh disc is made by hand thereby olfering much disadvantage, since it is difficult to take a cardboard disc out of the packing and to insert it properly. Also it may happen that the insertion of the fresh disc has been forgotten and finally the discs, if they are accessibly accommodated within the toilet room, are not protected from tampering and other usage.

The improvement according to the present invention obviates said disadvantage in connecting absolutely the feeding of the cardboard disc into the bowl of the toilet with manipulating of the cover, so that each fresh sealing disc will be automatically fed in that position in which it will be engaged by the plunger disc and pressed down into the sealing groove. For this purpose the cardboard discs are accommodated in a box, as a pile, arranged behind the toilet and forced against a sliding plate valve adapted at the upper end of the box. Said sliding plate valve closes the box on the upper end and has on its lower surface a catching edge or abutment engaging the upper cardboard disc. In manipulating the sealing cover the cardboard disc is pushed within range of the bowl and drops down toward the sealing section, whereupon the cardboard disc is pressed in position within the groove by operating the pressure lever. The sliding plate valve is extended towards the rear end so that a further feeding of the cardboard discs from the box is prevented as long as the toilet is suitable for further usage.

The accompanying drawing shows an example of the embodiment according to the invention, in which Fig. 1 is a vertical section of the toilet with two positions of the cover, i. e. the closed and the nearly open position, and

Fig. 2 is a partly section on line A-B of Fig. 1.

The dry toilet consists of a collecting receptacle a, the cylindrical intermediate sealing section b and the upper bowl c receiving the seat d. Within said sealing section there is the annular groove e into which the sealing disc f will be pressed down. The cover a carries in well known manner the operating stem or rod h with plunger disc i at its lower end, while the operating lever k engages its upper end and is connected with the seat by means of a compensating rod.

According to the invention dispensing means such as a box I is arranged behind the dry toilet, said box being open at the top and receiving the sealing cardboard discs accommodated in stacked relation as a pile, while a tension spring in is fitted below the cardboard pile. The box is provided at its upper end with lateral guides 11 receiving movably a sliding plate valve having on its lower surface a catching edge or abutment p and being equipped with an extension q towards the rear end. The sliding plate valve is disposed substantially at the level of the top end of said bowl and carries on the upper surface an eye r on its rear end with which engages a rod s connected with the operating lever k.

In using the dry toilet the cover g is moved toward the full-line position as shown in Fig. 1, whereby the operating lever k will be swung to uppermost position and the plunger disc 1' bears against the guide sleeve arranged in the cover g. It will be especially noted that the rod h carrying the plunger disc 1' is tightly fitted in the guide sleeve of the cover. After the toilet being used the operating lever k is returned in the position, as indicated by dotted lines in Fig. 1, so that the cover g rests on the seat d. During this manipulation the rod s will be actuated and causes displacement of sliding valve 0 in the lateral guides n by its connection with the sliding plate valve 0. The cardboard disc 1 lying at the top of dispensing means or box I is engaged by the catching edge p of the sliding plate and moved in the direction of the toilet bowl in such a manner that it drops down into the sealing section b. The rearward extension q of the sliding plate valve 0 comes now in the position over the box and closes the same with its full wall thickness towards the top, so that no further cardboard disc is able to come into feeding position and also any other tampering will be impossible. By pressure on the operating lever k the plunger disc i is moved downwards and the cardboard disc dropping in the meantime down into the sealing section is pressed into the annular groove 2, whereby the cardboard disc being already within said groove is discharged with the waste matter thereon into the collecting receptacle (1 and the fresh cardboard being at the top is pressed into the empty groove.

For subsequent use of the toilet the operating lever k is engaged and returned to its uppermost position, whereby the plunger disc i touches again the guide sleeve of the cover g. At the same time the sliding plate valve 0 is moved backwards by means of the extension q until the catching edge p has reached the top edge of the pile box. Owing to the pressure of the spring in the next cardboard dies 1 will be advanced into feeding position so that it abuts against the catching edge p in order to be moved again in direction of the toilet bowl by manipulating the operating lever k.

In the embodiment of the invention it is essential that the rod h of the plunger disc is tightly movable within the guide of the cover so that by pressing down the operating lever k the cover g is moved to rest on the seat of the toilet during which manipulation the cardboard disc will be then pushed in the range of the sealing section, whereupon then by further pressing down the operating lever k the plunger disc 1 can be moved in downward direction and the cardboard disc will be pressed into the annular groove e within the sealing section.

Although one specific embodiment of the invention has been described and shown in the drawing, it should be noted that the invention may be realized in modified form and adaptations of the arrangements herein disclosed may be made, as may readily occur to persons skilled in the art without constituting a departure from the spirit and scope of the invention as defined in the objects and in the appended claims.

What I claim to secure by Letters Patent is:

1. In a dry toilet having a bowl with an open top end, a collecting receptacle, a sealing section disposed intermediate said bowl and said collecting receptacle and adapted to receive a sealing disk, and a manually operable plunger for urging a sealing disk into the sealing section; dispensing means associated with said bowl for retaining a supply of sealing disks in stacked relation, a cover swingably mounted with respect to said bowl and supporting said plunger, slidable feeding means carried by said dispensing means substantially at the level of said top end of said bowl, and connecting means extending between said feeding means and said plunger, to thereby feed a single sealing disk into said bowl for engagement by said plunger upon swinging said cover downwardly against said bowl.

2. In a dry toilet according to claim 1, said feeding means including an abutment edge for engagement against the uppermost sealing disk of said stacked supply of sealing disks.

3. In a dry toilet according to claim 1, wherein said feeding means comprises a plate, said dispensing means being provided with a pair of guide members for slidably supporting said plate.

4. In a dry toilet according to claim 1, wherein said feeding means comprises aplate provided with an abutment edge for engagement with the uppermost sealing disk of said stacked supply of sealing disks, said dispensing means being provided with a pair of guide members for slidably supporting said plate.
